There has been quite a bit of talk on the net about Inauguration photos. Here are two sites where I have found some extremely moving photos - both the inauguration and the transfer of power. I highly recommend checking these out.
The Boston Globe has an outstanding series of photos called the "Big Picture". I was so looking forward to what they would post for the inauguration. It lived up to my expectations. I found the whole series very interesting and extremely moving. Not only great pictures of the day but also of the reaction world wide - Big Picture photos of the Inauguration
